Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed December 19, 1910. Serial No. 598,207.

following is a specification.

Our invention relates to improvements in a locomotive attachment and isdirected particularly to an improvement on such an attachment, forexample, as shown in U. S. Patent No. 975,870, heretofore granted to usNovember 15th, 1910.

in practice, we have found that in the use of such an attachmentas isshown and described in the United States patent above referred to,unless the steam is carefully regulated by the hand valve in theattachment, the following undes1rable results occur, viz.,

when the attachment is being used for melt ing alone, a sudden or heavypressure of steam will, under certain conditions, create an eddy in thesuction chamber and a re sulting back pressure on the steam hose whichis undesirable, while inthe use of the attachment to throw out thewater, the steam valve must be opened gradually to ad unit of priming.These features both require time and experience in operation, and anoffort to overcome these difiiculties and provide an attachment whichmay require no nicety of operation, and may be used with like results bythe experienced and inexperi enced, has inspired the present invention.

One of the objects of our invention is the combination in an attachmentfor locomotives of means for melting the snow and ice from frozenswitches and switch levers and of means for carrying away the waterresulting from the melting of ice and show so that it.

may not refreeze in the switches.

Another object of our invention is the pro vision of such an attachmentin which steam coming from the locomotive maybe directed against thefrozen. switch or switch levers,

or sent through aby-passto act as a water siphon.

of steam may be at once sent through a bypass and' which is self-primingat the coini'nencement of the siphoning.

'A still further object is the equipment of such an attachment with aguard for pre venting stones and earth being thrown back upon theoperator by the steam pressure.

Still further objects and purposes of our invention will appear from aninspection of the drawing, the specification describing the same, andthe claims appended thereto, in which are set forth the combination ofele ments, arrangement of parts, and novel structural detailspro perlycomprised within the same.

in the drawing in which is shown a preferred construction of ourinvention, Figure 1 is a view of the standard type railway locomotiveand tender showing the piping leading from the upper rear portion of thelocomotive boiler adjacent the steam dome to points on the engine andtender to which the attachment shall be connected. Fig. 2 is a generalview of our attachment showing only a fragment of thesteam hose forconnection to the engine piping. Fig. 3 is a longitudinal sectional viewof the attachment as shown in Fig. 2 on a somewhat larger scale.Referring now to the several figures in which like reference charactersdesignate like parts, (1) represents a locomotive and tender, (2) is apipe leading from the rear of the steam dome and terminating, in thepresent instance, at a plurality of points t) in the forward part of thelocomotive and at ment. In connecting the flexible steam hose (6) to thepiping (2) at (4) we use a standard coupling (5). The steam hose issuitably secured and connected at its other end to a short pipe (7)which is threaded into a three way valve (8) having an operating handle(8') therein. Extending in line with pipe (7) are the pipes (9 and 11)and the union (10), pipe (11) being threaded into the Y 12. Continuingfrom Y 12 and in line with pipes (7, 9 and 11) is the pipe (13) on whichis adjustably mounted a semi-circular shield (14) provided with a setscrew (1%) Extending from the three-way valve (8) at right angles to thepipes (7 and 9) is the pipe (15) bending at right angles to itself andprovided with the reducer (16). Connecting the reducer and the bushing(17) is the nozzle (20) passing through and terminating at the forwardend of the suction chamber (18), this nozzle being reduced at itsforward end as shown at 20. The suction chamber, which is properly a'T-fitting, is provided at its lower aperture with a member (19)perforated as at 19. Continuing from the forward part of the suctionchamber (18) is the pipe (21) bent approximately i5 degrees and threadedinto the hand valve Connecting the other end of this valve and the otherbranch of the Y 12 is a short pipe (23).

It must be understood that, exclusive of the elements 14, 14c, 16, 17,19, and 20, all of the elements from 7 to 23 may be standard pipefittings.

In operation, our attachment is coupled to the piping, and steam beingadmitted into the pipe (2), the steam pressure in the attachment isregulated by a valve at 3 so as to throw no back pressure upon the steamhose. The valve handle (8) is now thrown forward parallel to 9 and thevalve (22) closed. The course of the steam will therefore be directthrough the pipes 7, 9, 11, 13, and may be directed against the snow orice which it is desired to melt. The switch and switch levers beingproperly freed from the ice and snow, the valve (22) is now opened andthe valve handle (8) turned to the position shown in Figs. 2 and 3.Steam will now be cut ofi' from its direct passage and thrown throughthe bypass 15, 18, 21, 23. In issuing from the reduced portion (20) ofthe nozzle (20), the steam will create a suction in the suction chamber(18). The attachment is now placed with the perforated member (19) belowthe surface of the water that is to be removed. Owing to the com pactstructure of the suction chamber and perforated member, we obtain animmediate priming and the water is now siphoned out through 21, 23, 12,and 13 and discharged at some place in which its freezing will notaffect the switches or switch levers.

By providing the valve (22) we prevent any back current of steam whenthe attachment is employed for melting the ice. The shield (14:) hasbeen found desirable where the switch levers extending from the rails tothe switch proper lie in a cinder depression, in that the cinders areprevented from flying back against the operator. By providing ourattachment with a by-pass and threeway valve for directing the steameither in its direct course or through the bypass we have obviated allnecessity of adjustment after the valve has been opened to the requisiteextent by the operator.

We claim 1. In a locomotive attachment, the combination of apparatus fordirecting live steam against a frozen switch, with apparatus forsiphoning water away from the switch levers, and means for renderingeither apparatus inoperative during the operation of the other.

2. In a locomotive attachment, the combination of direct piping forthrowing live steam against a frozen switch, with a bypass on saidpiping for siphoning water, and means for cutting ed the steam from thedirect piping and sending it through the siphoning by-pass, as and forthe purpose set forth.

3. In a locomotive attachment, the combination of direct piping, abypass leading from said piping adjacent to its end and reconnected withthe piping toward the other end, siphoning apparatus located on thebypass intermediate its ends, and means for closing either the bypass orthe piping adjacent the rear end of the latter, as and for the purposeset forth.

1. In a locomotive attachment, the combination of direct piping, abypass in said piping, siphoning apparatus located in said by-pass, anda three way valve located in the rear union of the piping and by-pass,as and for the purpose set forth.

5. In combination, a railway locomotive, pipes leading from the boilerand terminating at a plurality of points on the engine and tender, handvalves adjacent the termini of said pipes, an attachment comprisingstraight piping having a bypass thereon, siphoning apparatus located inthe by-pass, a steam hose connected to the piping, means for couplingthe hose to a pipe terminus, and means on the attachment for directingsteam through either the straight piping or the by pass.

In an apparatus of the class described, the combination of a railwaylocomotive, piping leading from the locomotive boiler and terminating ata plurality of points on the engine and tender, with a member, adaptedto be coupled to said piping for directing live steam against a frozenswitch and having a shield thereon, as and for the purpose set forth.

7. In a locomotive attachment, the combination of piping, a bypassthereon, a threeway valve at one end of the by-pass, a valve adjacentthe other end, and siphoning apparatus in the bypass and between saidvalves.
